Introduce a root GET route that serves a minimal HTML landing page describing the Pyrogram Bridge service and linking to its GitHub repository. This provides a friendly entry point for users accessing the service via a browser.
Previously NEW_CHAT_TITLE events were ignored in the RSS generator,
preventing title updates from being included. The filter line has been
removed so these messages are now processed correctly.
Replace string comparisons with the MessageMediaType.POLL enum and add the
necessary import. This ensures poll messages are correctly identified and
skipped during media processing.
Update poll handling to extract the `text` attribute from question and option objects when present, falling back to string conversion otherwise. This ensures proper rendering of poll content from Telegram objects that expose a `text` field.
Add a new `mime_type` column to the media_file_ids table and provide
functions to get and set cached MIME types. The API now attempts to
retrieve the MIME type from the database before falling back to
python-magic, persisting the detected type for future requests. This
reduces I/O overhead and improves response performance. Also adjust
logging to debug level to reduce noise.
Implement HTTP Range request support by replacing FileResponse with StreamingResponse.
Added async chunked generator, proper Content-Range, Accept-Ranges, and filename encoding headers.
Updated imports, endpoint signature, and background cleanup handling.
Switch persistence of media file identifiers from a JSON file to a
SQLite database. Introduce DB_PATH, init_db_sync, upsert, update, and
removal functions. Remove json-repair dependency and related locking
logic. Update api_server and post_parser to use the new database
helpers.
BREAKING CHANGE: media_file_ids.json is no longer used; existing
data must be migrated to the new SQLite database.
The proxy configuration now uses a SOCKS5 scheme instead of MTProto. The default port is updated to 1080 and optional username/password fields are supported. Docker compose comments are updated accordingly.
BREAKING CHANGE: existing MTProto proxy settings (scheme "mtproto", port 443) are no longer supported and must be migrated to SOCKS5.
Introduce optional MTProto proxy configuration sourced from environment variables, expose related settings in `config.py`, document the variables in `dockercompose.yml`, and pass the proxy configuration to the Telegram client initialization.
Add a `_shutting_down` flag to `TelegramClient` to suppress disconnect handling during intentional shutdown. The flag is set before sending SIGTERM in `_restart_app` and checked in `_on_disconnect` to ignore those events. Minor formatting adjustments were also applied to `api_server.py` (try block and `uvicorn.run` arguments).
Add monotonic timing instrumentation around media download, semaphore
wait, HTML sanitization, and media file persistence. Log warnings when
operations exceed defined thresholds and provide diagnostic info for
task queue size. This aids performance monitoring without altering
behaviour.
Separate live HTTP media requests and background cache workers by introducing `HTTP_DOWNLOAD_SEMAPHORE` and `BACKGROUND_DOWNLOAD_SEMAPHORE`. Remove the previous global `DOWNLOAD_SEMAPHORE`, diagnostic event‑loop monitor, and related logging. Refactor `download_media_file` to handle large videos with temporary files, clean up zero‑size cache entries, and update access timestamps without semaphore tracking. Adjust background worker and request handling to use the new semaphores, simplifying concurrency control and eliminating unnecessary diagnostics.
Introduce a periodic event‑loop monitor that logs active tasks, semaphore
state, queue size and thread‑pool activity. Track the number of coroutine
waiters for the download semaphore and emit detailed diagnostic logs in
download handling and the background worker. This aids debugging of
concurrency and resource‑usage issues.
The changes ensure that when `show_caption_above` is true, text content is rendered before media, and when false, media is rendered before text. This aligns the actual rendering order with the semantic meaning of the flag, fixing a bug where content ordering did not match user expectations.
Add support for Telegram's show_caption_above_media message attribute to conditionally order caption and media content in HTML output. When enabled, media is rendered before the text caption instead of the default text-before-media order.
Logs the date range (oldest/newest) and total count of posts being added to RSS feeds, plus debug-level logging for each entry's timestamp conversion. This improves observability for feed generation and helps diagnose date-related issues.
Add flood wait exception handling in both RSS and HTML generation functions.
The bot now automatically waits for the specified duration and retries the
operation when encountering rate limiting from Telegram's API.
Add queue-based background download system to improve performance and reliability:
- Introduce DOWNLOAD_SEMAPHORE to limit concurrent downloads to 3
- Add asyncio.Queue (maxsize 100) with dedicated worker for background processing
- Implement safe_get_messages and safe_download_media wrappers with timeout protection (30s and 120s)
- Add retry logic for KeyError auth failures with 5s backoff
- Replace synchronous sequential downloads with asynchronous queued processing
- Prevent event loop blocking by queuing files instead of immediate download
